BALL-COCK VALVE.

SPECIFICATION forming' part of Letters Patent No. 669,146, dated March5, 1901.

Application filed May 16, 1898.

To a/ZZ whom it may concern.-

Be it known that I, JOHN PoRTEoUs, a citizen of the United States, and aresident of Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Ball-Cock Valves,of which the following is a specification.

The object of my invention is to provide an easy-moving and reliableball-cock valve especially designed for use in flushing-tanks forwater-closets which is inexpensive in construction, not liable to getout of order, noiseless in use, and not liable to leakage when the valveis closed upon its seat to cut off the supply of water to the tank.

With this object in view my invention consists in the peculiarconstruction and arrangement of parts illustrated in the accompanyingdrawings, in connection with which the invention will be first fullydescribed and then particularly referred to and pointed outin theclaims.

Referring to the drawings, Figure l is a vertical longitudinal sectionof a flushingtauk provided with my valve, the valve being shown in axialsection and in the open position. Fig. 2 is a detail view faken throughthe valve in the same plane as Fig. l, but with the valve in the closedposition.

Referring to the parts, which are indicated by similar reference-letterswherever they occur throughout both views, A represents theflushing-tank, the bottom A of which is perforated near one end toreceive the shank b of the Valve-case B, which has flanges b at thebottom of the case, and the lower end of the shank screw-threaded toengage the flanged nut b2, which clamps and rmly holds the valve-case inplace on the bottom A of the tank. The lower end of the shank Z) isfunnelshaped to receive the cone end of the supplypipe C, which istightened into the lower end of the shank b bya box or tubular nut c,which is centrally perforated, leaving a plain flange around theperforation to engage the shoulders under the cone-shaped end of thesupplypipe C. The parts above described, excepting the case B of thevalve, are well known and need not therefore be more specicallydescribed.

The valve-case B, with its shank b, is cast Serial No. 680,795. (Nomodel.)

in a single piece, having the entry and discharge port divided by atransverse partition perforated centrally below the upper opening andturned or dressed cone-shaped to receive the cone-shaped elastic valved, which controls the supply of water to the tank, the discharge-spoutb3 being on a level with the upper edge of the flange which rests uponthe bottom A' of the tank, so that the water is noiselessly dischargedagainst the bottom of the tan k. The upper end of the case isscrewtapped to receive the upper extension b4 of the valve-case, theenlarged perforation in the lower end of which is dressed true to seatthe elastic valve cl', which is preferably made of a leather disk andwhen in position, as seen in the drawings, assumes a .cup shape, leavingan opening between it and the stem or shaft d2 of theinverted-cup-shaped part cl3, which incases the elastic valve d, whichis held in place by a nut d4 on the lower screw-threaded end of a shankd5 of an actuating valve-stem D, which slides freely in the reducedperforation of' the upper extension b4. The enlarged part of the stem Dhas an annular ange around its lower edge to bear against a shoulderdividing the larger and smaller perforations in the upper extension tolimit the upper movement of the valves d and d. The end of the neck orstem cl2 is rounded on its upper edge and screw-threaded interiorly totighten the elastic valve d against the shoulder of the enlarged stem D.

It will be seen that a space is left between the cup-shaped part of thevalve d and the shank d2 to receive the water under pressure and keepthe cup-valve closely to its seat to prevent leakage and also to insurea steady even movement of the valve in either opening or closing of bothvalves olV and d.

The upperend of the stem D is transversely slotted to receive thecam-shaped end of the actuating-lever E, which is journaled in lugs b5,which project from one side of the upper extension b4. The outer end ofthe lever E is screw-threaded to receive the arm e, by

which it is connected to the float E', the weight I of which opens thevalve when the Water in the tank is discharged to flush the bowl andwhich when the ordinary discharge is closed keeps the valve open untilthe water rises in IOO the tank, carrying the iloat up and closing thevalve d on its seat, as clearly shown in Fig. 2.

It will be seen that either in the closed or opened position of thevalve d no leakage can occur through the top or upper extension of' thevalve-case and that by reason of the outward pressure of the waterbetween the stem d2 and the cup-shaped valve d there would be sufficientfriction between the edge of the cup-shaped valve and its casing toinsure a steady movement and prevent any dancing or jerking movement ofthe valves in either opening or closing, thus avoiding,` the splashingand noise incident to valves of this class that are liable to be thrownsuddenly from one position to the other. It will |also be seen that bybringing the discharge-opening of the valve-case down to near the bottomf the tank or just above the clamping-flange which sustains thevalve-case in place a great saving of' metal and work is accomplishedand the inflow rendered entirely noiseless.

I have shown the controlling-valve d coneshaped to fit a cone-shapedseat in the partition of the case, and I prefer to make it in this wayand incase it in the cup d3, because it can be expanded outwardly to'make a close fit with the seat in case of wear by simply tightening upthe nut d4 on the lower end of the screw-threaded shank.

What I claim is- 1. In a ball-cock valve the case-body provided with amain-valve seat above the discharge-port and an upper extension to guidethe main valve and the piston-valve, said upper extension having anenlarged Abore provided With an offset to furnish a seat for a flangedvalve .around the guidestem, the valve-stein fitted to slide in theupper bore of the extension and having: a flanged valve to seat againstthe shoulder of the larger extension and provided with a screw threadedshank to receive the cup-shaped valve at its upper end and the maincontrolling-valve at its lower end, the actuating-lever to recipro-'cate the stern to open or close the valves whereby the flanged valve onthe lower end of the guide-stein makes a water-tight joint to preventthe water passing' through the u pper extension when the valve is open,should any leakage oceu r past the pistonwalve.

2. In a ball-cock valve of the character described the combination ofthe valve-case having an upper extension lto guide the valvestem and anenlarged extension to furnish a seat for an elastic cup-valve and havingthe offset between the upper and lower bore forining a valve-seat, thevalve-stem having its upper end turned to t the smaller bore of theupper extension to guide the siem truly and having a flanged valve belowthe' guide portion of the stem to close against the seat in said upperextension', a screw-threaded shank below said flanged valve, an elasticcup-valve at the upper end of the screwthreaded shank, acontrolling-valve at its lower end and the supplemental shan k-serewtapped to hold the elastic valve in place and having a cup-shapedextension at its lower end to hold the elastic controlling-valve,substantially as shown and described.
